convert regular expression from c# to javascript

Question

Can someone help me convert this c# regular express (email validation) to Javascript?

@"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$

That looks like a simple regex for email addresses. I'm kinda sure that's actually not what it does (well). — Grant Thomas, Apr 26 '13 at 13:38

It should work pretty much as is¹:

var address = . . .;
var r = /^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;

if (address.match(r)) {
    // address is okay
}

¹ That is, it should work in JavaScript as well as it does in C#. Email validation is actually quite complex and your C# regex is really not very good for this. See this thread.
